Application May 31, 1950, Serial No. 165,340

1 Claim. 1 This is a continuation-in-part: of" my copending application Serial Number 107,120. which was filed on July 27', 1949, now abandoned.

This invention relates to improvements in rail joints.

. and loweredge of each extension.

Another object of this invention is to provide a rail joint as aforesaid which has a pair of plates connected therewith, each plate engaging one extension and a part of the two confronting rails and each plate bearing against the undersuri'ace' of the rail ball to prevent downward vertical movement of one rail or extension with respect to the other thereby assuring a plane and smooth upper surface for the ball of the rail.

Ancillary objects and features of importance will become apparent in following the description of the illustrated form of the invention.

In the drawings:

Figure 1 is a perspective view of the rail joint assembly and shows fragmentarily a part of a pair of railroad ties;

Figure 2 is an exploded perspective view of the base plate, side plate and counter plate forming an important part of the invention;

Figure 3 is an exploded perspective view of the extensions;

Figure 4 is a transverse sectional view taken substantially on the line 44 of Figure 1 and in the direction of the arrows, and;

Figure 5 is a horizontal sectional view of the assembly taken substantially on the line 55 of Figure 1 and in the direction of the arrows.

There is a pair of conventional ties Ill and i2 respectively illustrated in Figure 1 and arranged thereabove is a pair of rails I4 and I6 respectively.

This is the setting or environment of the instant invention. The rail [4 is provided with a web [8, a ball 2!] on the top edge thereof and a base 22 on the lower edge thereof. The rail 14 is of standard stock, as is the rail IS.

The rail [6 includes a base 24, a Web 26 and a ball 28 fixed integrally with the upper edge of the web 26.

Extensions 3!] and 32 are integrally formed with the rails l4 and I6 and are arranged in 2 confronting relationship. The extensions are rabbeted together.

Reference is made to the extension of Figure 3 wherein the ball section 34 is shown at the upper edge of the web 36, said web 36 being disposed on and fixed to the base 38. The base and extension ball 34 are one-half the size of the rail ball 20 and rail base 22, but the web is of the same thickness as the web I8.

The extension 32 is provided with a ball section 4-0 on a Web 42 which is fixed toand which rises from the base 44. The base 44 and ball section 46' are one-half the width and sizeof the ball 28 and base 24, but the web 42 is of the same thickness as the web .26 of the rail it.

Accordingly when the sections are in confront- I ing relation as disclosedin Figure I, the effective web, thus formed, is twice the thickness offeith'er web [8 or 2B.

Elliptical openings 45 and 48 are formed in the extension 33, while the elliptical opening 49 is formed in the web it. Openings 5B and 52, which are also of elliptical shape, are formed in the web 42 and an elliptical opening 54 is formed in the web 26. The opening 46 is adapted to match with the opening 50, while the opening 48 is adapted to be in alignment with the opening 52 when the extensions are in confronting relationship. Therefore, the bolts 56 and 58 pass through the pair of openings 48 and 52 and the pair of openings 46 and 50 respectively. The nuts 59 and 6!! which are disposed on the bolts 56 and 58 hold the extensions assembled in the condition disclosed in Figure 1.

Attention is now invited to Figure 2 wherein there is disclosed a holder for the extensions and the rails l4 and [6. The holder consists of a base plate 64 which has a side plate 66 secured thereto. as by forming it integrally therewith or welding. A vertically rising shoulder 68 is fixed to the base plate 64 but spaced from the side plate 66. A counter plate HI has its lower edge disposed in abutment with the shoulder 68 (Figure 4) and the counter plate 10 is shaped to conform to the shape of the side of the web and the upper surface of one side of the base 22. The side plate 66 is of a similar shape and is adapted to contact a web 42, a part of the base 24, the base 44 and a part of the base 22. It will be noted from inspection of Figure 4 that the counter plate 10 and the side plate 66 fit very tightly against the outside surfaces of the extensions and are of sufficient height to bear against the bottom surface of each ball section 34 and 46 respectively. The purpose of this abutment is to prevent one extension from moving vertically downward with respect to the other one so as to open the joint. The side plate 66 cooperating with the base plate 64 forms a pocket in which the extensions are disposed, and the base plate is disposed upon at least one and preferably two ties l and I2.

Notches T6 and I8 are formed in the base plate 64 at one side thereof to accommodate the spikes and 82 which pass into the railway ties I0 and I2 to thereby anchor the assembly. Notches 84 and 85 are formed in the shoulder 68 to form seats for the spikes 88, the last mentioned spikes being disposed in the ties I0 and I2 to further insure anchorage of the assembly.

The bolts 56 and 58 pass through the aligned openings and 9| and 92 and 93, these openings being elliptical and formed in the side plate 66 and counter plate I0.

The bolts 94 and 95 pass through the'elliptical openings 95 and 9?, formed in a pair in the ;counter plate I0 and side plate 66 and through the pair of aligned elliptical openings 98 and 99 also formed in said plates 56 and I0.

Thebolts 94 and 95 pass through the openings 49 and 54, which are formed in the webs l3 and 26 and also pass through openings I00 in the shims IOI, I02, I93 and the other necessary shim which is unshown but which is located behind the shim I9! (see Figure l).

The shims are necessary inasmuch as the extension webs 35 and 38 are each double the thickness of the webs I8 and 29 of the rails I4 and I6.

Attention is invited to Figure 4. The surface I06 of the web 39 is transversely concave, while the surface I08 of the extension web 42 is also transversely concave. By this expedient the confronting surfaces I06 and I08 do not contact each other except at the top edge thereof and the bottom edge thereof which is in the region of the ball sections 32, 34 and the base sections 38, 44.

Such a construction to my knowledge is new and is of major importance inasmuch as the ball sections at the top parts thereof or of top surfaces thereof will be fastened firmly together in contact with each other and this is the portion on which 4 the rolling stock rides. The same is true at the bottom of the assembly, that is, it is of major importance inasmuch as a firm gripping frictional contact is made.

Having described the invention, what is claimed as new is:

An assembly for connecting confronting ends of rails which have bases with webs rising therefrom and rail balls at the upper extremities of the webs, said assembly comprising an ofiset extension of each of said rail webs and balls in nested relation, said extensions having apertures therein and provided with concave confronting sides, means disposed in said apertures to pull said concave confronting sides together and to hold said extensions assembled, a base plate disposed below the bases of said extensions, a side plate rising from said base plate and engaging one of said extensions and the ball of said one of said extensions, said means being passed through openings in said side plate, a shoulder fixed to said base REFERENCES CITED The following references are of record in the file of this patent:
